You should call the set of system property as soon as possible.
There is some "entry point", a servlet maybe ?
If not you can write your own servlet and set <load-on-startup> to 1.
And you have to call configure() again because if you have log4j
configuration file
on classpath it will be configured automtically before you can do anything.
Calling configure() after system property is set will cause log4j to be
able
to use this system property.

Subject: Re: SMTPAppender , server instance
I will like to try the second approach , my log4j is initialized by
spring , I have
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
in my web.xml.
Please tell me where should I call System.setProperty("HOSTNAME",
InetAddress.getLocalHost
().getCanonicalHostName());
do I also have to call
DOMConfigurator.configure(getClass().getClassLoader().getResource(
"log4j.xml")); ?
